For causing Iran and other countries to suffer, perhaps we're degenerating per Karma or universal justice. We can cherish and preach "Love thy neighbor as thyself," and should. But, watching our destruction, for all we work to save ourselves, perhaps we should also say, "Let it be." Let things run their course. The ultimate courage, perhaps, is to trust that, cosmically, all is well, and all shall always be well.
Nothing happens until something is disrupted.
